Answer
Step Q is associated with the breakdown of proteins into smaller peptides, which is facilitated by peptidases. Therefore, the conclusion is logical.
Step 2
B. step R involves the joining of proteins to form polypeptides.

Answer
Step R is focused on the reassembly of peptides into larger polypeptides. This process aligns with the conclusion drawn from the diagram.

Answer
This statement can be inferred as children inherit genetic material from their parents, influencing the proteins synthesized, leading to similarities in their proteomes.
Step 4
D. the number of amino acids in the mixture containing all proteins is the same as the amino acids in the separated peptides.

Answer
This conclusion holds since the total number of amino acids remains unchanged when the proteins are separated into peptides, assuming no loss occurs during the process.
